Primary intraosseous squamous cell carcinoma is a rare malignant central jaw tumor derived from odontogenic epithelial remnants. Predominantly, it affects mandible, although both jaw bones may be involved. This report describes a 60-year-old man who was initially misdiagnosed with a periapical infection related to the right lower wisdom tooth. After four months, the patient presented to a private dental clinic with a massive swelling at the right side of the mandible. Panoramic radiographs and advanced imaging revealed a lesion with complete erosion of the right ramus, which extended to the orbital floor. A biopsy from the mandibular angle revealed large pleomorphic atypical squamous cells, which is the primary microscopic feature of a poorly differentiated squamous cell carcinoma.

Objectives : Based on data collected from patients who suffered from dental caries during the period between 1990 and 2008, the number of patients and their trends were analyzed as a source of evidence to conduct the oral health plan. Methods : A population of sample design for patient survey data was derived from computerized data saved at medical institutions accredited by National Health Insurance Corporation. Large institutions such as dental hospitals were included for the complete enumeration test, while the rest of medical institutions, for example, dental clinic, relatively small institutions, were used for the sample survey. Most of patients with dental caries were outpatients and their disease was treated at the dental hospital or dental clinic in general, therefore, main analysis was carried out at those institutions. Results : The rate of patients who suffered the dental caries has decreased to 56.8% in 2008 from 78.5% in 1990. The rate of patients who visited the dental hospital for treatment has increased to 4.8% in 2008 from 0.5% in 1990, whereas the percentage of those who visited the dental clinic has fallen to 97.9% from 99.5% during the same period. The ratio by age, in the meantime, it showed that patients aged 40s has increased to 13.5% in 2008 from 7.2% in 1990, and the number also has risen in 50s from 5.6% in 1990 to 9.9% in 2008. However, the number of children aged 0 to 9 who visited hospital for treatment of dental caries has fallen to 17.0% in 2008 from 33.9% in 1990. Conclusions : By figuring out the trends of patients with the dental caries during the period between 1990 and 2008, fundamental data for the oral health policy have been collected. As a result, the necessity of a new medical treatment system for managing the dental caries in terms of patient ages as well as the oral health policy and campaign was taken into consideration.

Objectives : The objective of this paper is to clarify the factors of the geriatric oral health influencing oral health-related quality of life by using the contracted OHIP-14 tool. Methods : This research conducted individual interview for 177 seniors using senior citizen center by using structured questionnaires. SAS(Ver.9.2) Program was used for the collected data to perform frequency analysis, reliability and scale analysis, t-test, ANOVA, correlation analysis and multiple regression analysis. Results : The oral health-related quality of life level related to oral health according to the demographical characteristics showed that it was better in case that they are younger, married, more educated and have more living expenses. Except for age, oral health-related quality of life was connected to scholastic achievement, living expenses, subjective health condition and subjective oral health condition. The factors influencing the oral health condition were subjective health condition, marriage, scholastic achievement, living expenses, age and sex. As the subjective health condition is better, in case of cohabitation of only a couple and as the age or scholastic achievement is higher and the living expenses are more, the oral health condition was better. The factors influencing oral health-related quality of life were subjective oral health condition, marriage, sex, subjective health condition, scholastic achievement and living expenses. As the subjective oral health condition and health condition were better and in case of sole living and cohabitation of only a couple, male's oral health-related quality of life was higher. Conclusions : It is considered that because the geriatric oral health condition becomes an important factor to oral health-related quality of life, the development of the geriatric oral health business and the geriatric heal education program to maintain and improve oral health is required and the activation of the oral health insurance policy for preventive dental service is necessary.

This study was conducted to identify factors related to discomfort while speaking in the elderly and provide fundamental data for establishing oral health care policies for a healthy old age. Using the raw data from the 8th wave of the National Health and Nutrition Examination Survey (2020), we conducted an analysis to examine the relationship between speaking discomfort and mental health, as well as oral health care behavior, among 1,278 elderly individuals in Korea. Differences in speaking discomfort were analyzed based on general characteristics, mental health, and oral health care behavior using complex sample cross-analysis. Additionally, factors associated with speaking discomfort were analyzed using complex sample multiple logistic regression analysis. As a result, individuals with depression experienced higher levels of speaking discomfort (p<0.05), and individuals experiencing high levels of stress also reported higher levels of speaking discomfort (p<0.05). As a factor affecting speaking discomfort, it was found that speaking discomfort was 2.56 times higher (p<0.001) when dental care was not met, and speaking discomfort was 3.05 times higher (p<0.05) when teeth brushing was less frequent. As a result of the aforementioned findings, it is believed that a customized oral health promotion program is necessary to expand dental health insurance coverage for the elderly and improve oral healthcare.

Nowadays, dental tourism becomes phenomenon because of its cost-effectiveness, improvement of quality and technology, dental infrastructure, and attractive tourism. Korea as one of popular destination country had established dental system. On the other hand, Indonesia with high number of population is potential market for dental tourism. The aim of this study is to compare the knowledge, attitude, and experience towards dental tourism among Indonesian and Korean. Two cross-sectional descriptive surveys were conducted to collect the data. This study was used one questionnaire in two different languages due to nature of the study population. Data from a total 923 of Indonesian from 33 provinces in Indonesia was collected during the period from April through July 2010. On the other hand, during May until August 2010 data from a total of 312 Korean were obtained. It was found that the majority of participants in both countries had never heard about dental tourism. Among those who had heard about dental tourism, the most common source was internet. Ownership of dental insurance had significant relationship with knowledge of dental tourism among Indonesian while level of education and monthly internet usage had it among Korean (p<0.05). Attitudes of Indonesian and Korean people about dental tourism were negative due to assumption that dental services in their home country were satisfactory. 100% of Korean had no experience on dental treatment in other countries while 2.4% of Indonesian had experience with it. In conclusion, regarding all these evidences, comprehensive and positive information about dental tourism is needed to enhance people's knowledge, attitude, and experience.

Relative value scales introduced in 2001 remarkably improved health insurance fee schedule, but current relative value scales have many problems. In the beginning the government intended to introduce 'resource based relative value scales(RBRVSs)' like USA, but political adjustment of RBRVS studied in 19.17 weakened the relationship between relative value scale and resource consumption. So unbalance of health insurance fees are existing till now. Also relative value was not divided to physician work and practice expense, and malpractice fee was not divided separately. To correct the unbalance of current relative value scales, the refinement project of health insurance relative value scales started in 2003. The project team divided relative value scales into three components, which are physician work, practice expense, malpractice fee. Physician work was studied by professional organizations like Korean medical association. To develop the practice expense relative value, project team organized clinical practice expert panels(CPEPs) composed of physicians, nurses, and medical technicians. CPEPs constructed direct expense data like labor costs, material costs, equipment costs about each medical procedures. The practice expense relative values of medical procedures were developed by the allocation of the institution level direct & indirect costs according to CPEPs direct costs. Institution level direct & indirect costs were collected in 21 hospitals, 98 medical clinics, 53 dental clinics, 78 oriental clinics, and 46 pharmacies. The malpractice fee relative values were developed through the survey of malpractice related costs of hospitals, clinics, pharmacies. Putting together three components of relative values in one scale, the final relative values were made. The final relative values were calculated under budget neutrality by medical departments, that is, total relative value score of a department was same before and after the revision. but malpractice fee relative value scores were added to total scores of relative values. So total score of a department was increased by the malpractice fee relative value score of that department This project failed in making 'resource based' relative value scales in the true sense of the word, because the total relative value scores of medical departments were fixed. However the project team constructed the objective basis of relative value scale like physician's work, direct practice expense, malpractice fee. So step by step making process of the basis, the fixation of total scores by the departments will be resolved and the resource based relative value scale will be introduced in true sense.

Objectives: This study aimed to understand the nationwide patterns of antibiotic prescription after tooth extraction in adult patients. Materials and Methods: This study analyzed dental records from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) database on 503,725 tooth extractions performed in adults (≥19 years) during 2011-2015. Patient sex, age, household income, systemic disease (diabetes mellitus and hypertension), type of dental institution, region of dental institution, year of prescription, and type of tooth extraction procedure were considered. The antibiotic prescription rate and broad-spectrum antibiotic prescription frequency were analyzed using chi-squared tests. Factors affecting the prescription of broad-spectrum antibiotics were evaluated using multivariate logistic regression analysis. Results: The rate of antibiotic prescription after tooth extraction was 81.85%. Penicillin was most commonly prescribed (45.25%), followed by penicillin with beta-lactamase inhibitors (18.76%), metronidazole (12.29%), and second- to fourth-generation cephalosporins (11.52%). The proportion of broad-spectrum antibiotics used among all prescribed antibiotics was 45.88%. Conclusion: The findings of this study demonstrate that the rate of antibiotic prescription after tooth extraction is higher in Korea than in other countries. Furthermore, broad-spectrum antibiotics are used more frequently, which may indicate unnecessary drug prescription, an important contributor to antibiotic resistance.

Objectives: Using data from the 1styear of the 7th National Health and Nutrition Survey, this study administered a questionnaire to patients with oral damage and examined the type of medical care used based on the nature of the injury, further characterized by age group and sex. Methods: Of the 8,150 respondents, this study selected those who participated in the health survey and oral exam survey, excluding surveys with missing values, and set 7,681 people as the research participants. This study used SPSS Windows version 23.0(SPSS Inc. IL, USA) as the statistics program and applied the chi-square test (p) based on a complex sample and logistic regression analysis. Results: In the analysis of the type of tooth damage, there was a significant difference (p<.001) in the number of male patients who were injured due to exercise, violence, and safety accidents compared to females. However, there was no significant difference in their type of medical security and whether or not they visited a dental clinic. The patients with private insurance showed relatively high use for tooth extraction and oral surgery (p<.001). Conclusions: The best way to prevent tooth damage is to prevent the accident. For sports or exercises which may cause tooth damage, protective gear, such as a mouthpiece, should be used to prevent tooth damage.

This study aimed to investigate the frequency of dental visits after coronavirus disease 2019 (COVID-19) in children and adolescents in comparison to that of adults. The data on the number of dental visits on the basis of different classification and treatment codes for all the age groups were provided by the Health Insurance Review and Assessment Service from January 2017 to December 2020. To reduce the impact of the population change, dental visits per 1000 people was used. After the start of the pandemic, dental visits per 1000 people decreased in all age groups when analyzed for the diseases of pulp and periapical tissues classification code and dental visits per 1000 people decreased over 5 years age groups when analyzed for the pulp treatment code. Regarding the restorative treatment code, visits in the 0 - 19 years age group decreased after the pandemic. Based on the comparison of the number of confirmed COVID-19 cases to that of monthly dental visits by treatment codes, the change rate of pulp and restorative treatments gradually decreased after the waves of the pandemic in February and August 2020 in Korea. Furthermore, dental visits per 1000 people for gingivitis and periodontal disease classification code increased after the pandemic in all age groups. The rate of decrease in dental visits per 1000 people for restorative treatments in children and adolescents was higher than that in adults. The rate of decrease in the number of dental visits for multi-visit pulp treatments showed a rapid decrease as compared to that of 1-visit pulp treatments after the pandemic. This study identified changes in the number of dental visits of children and adolescents after COVID-19 transmission in comparison to that observed in adults.
